[QUOTE="257Tony, post: 1855726, member: 67337"] Also, R22 especially is not temp stable, so your hot barrel/chamber could be increasing velocities/pressure, changing your groups for the better. Switch to a temp stable powder, run a ladder, and see what that does for you. H1000/Retumbo, or 7977/8133 might be good choices. After you take care of the bedding issues, of course. [/QUOTE]
